Here is how the 49ers (10-4) graded in their 33-14 win over the host Tampa Bay Buccaneers (4-10):

Pass offense: Colin Kaepernick's ability to extend plays was best illustrated when he rolled right and repeatedly found Michael Crabtree, who had his first touchdown of the season. But Kaepernick also showed he can unleash fury from the pocket, doing so on a 52-yard laser for a Vernon Davis touchdown. Anquan Boldin made the most of his three catches, leaving Darrelle Revis in the dust on one. They still need more out of their backup tight ends, including Vance McDonald, who was a (healthy?) scratch for the first time. Grade: A

Run offense: Frank Gore, Kendall Hunter, LaMichael James and Kaepernick found wide lanes to run through thanks to solid blocking and inferior tackling. Gore busted four runs for over 10 yards, and his 86 total yards rolled his season odometer over the 1,000-yard mark for the seventh time in his illustrious career. Of Kaepernick's four carries for 42 yards, two were for first downs on the opening touchdown drive. (Note: the official stats incorrectly had Kaepernick with seven carries for 39 yards after assigning him the final three kneel-downs, which actually were taken by Colt McCoy; center Jonathan Goodwin kindly confirmed this via Twitter.) Bruce Miller's left-arm injury looms as a heavy concern. Grade: A

Pass defense: Tramaine Brock sure plays with fire, and he came up with a humorous celebration for a third-down pass defense: pretend to punt. Aldon Smith (two sacks) and Justin Smith (one sack) are ramping up their efforts at the right time, though the later has been exceptional all season and worth team MVP honors. Tarell Brown returned to action as the No. 3 cornerback but was relegated to the left side for the first time since 2010. Both Bucs touchdowns came on passes. Grade: A-

Run defense: Tampa Bay attempted only three runs after halftime, surrendering after 12 total carries netted them just 39 yards. Aldon Smith made a shrewd tackle for a 2-yard loss. Patrick Willis had a team-high six tackles. Kaepernick's counterpart, Mike Glennon, wasn't a threat to run and had no carries. Grade: A

Special teams: Phil Dawson went 4-for-4 and has now made 24 consecutive field-goal attempts, a franchise record. But the special-teams show-stopper came with Kendall Hunter's touchdown return of a botched reverse on a fourth-quarter kickoff. LaMichael James fared well by averaging 10.2 yards on five punt returns. Grade: A

Coaching: They kept their players focused after a big win over Seattle, and no turnovers were committed against the league's leader in takeaways. Those were last week's focal points. Jim Harbaugh's staff looked even more brilliant when compared to a Bucs squad that ordered a foolish fourth-quarter reverse on a doomsday kickoff return. Replay challenges aren't the 49ers' best feature. Not a great sign when you're 4 ½ minutes into a game and you're down to one timeout then also draw a delay-of-game penalty. Grade: A-
